If you are building residential condominiums in Ontario, you must attend an interview with a Tarion representative.

If you are planning to build a high-rise condominium project and Part 3 of the Ontario Building Code applies to any element of the project, then you must comply with the design and site review requirements of Builder Bulletin 19R.

All condominium builders are required to complete a Condominium General Review Form. You can request a copy of the form by calling the Licensing and Underwriting Department at 1-877-696-6497 ext. 3001 or sending an e-mail to: L&U@tarion.com.
After you submit the form, and your risk assessment is completed, you will be advised of the security requirements for the project. Security must be posted prior to registration with Tarion and/or the taking of deposits and the signing of purchase agreements.

All units must be enrolled with Tarion at least 30 days prior to the start of construction and/or marketing (See Builder Bulletin 27​).
